HowTo install Redmine on CentOS (Detailed)


CentOS is one of the most frequently chosen Linux operating systems for Linux based production environments. There is extensive documentation available on setting up CentOS and it is arguably the best choice for deploying and running production Linux servers for organisation with all levels of in-house Linux server deployment and administration capability.

Redmine is one of the best (if not THE best) open source issue tracking and project management applications, but because it is developed using Ruby on Rails it can be rather complex to deploy for anyone not familiar with the Ruby on Rails environment.

This How-To provides detailed steps required to get Redmine up and running on a CentOS operating system using the following components:
  • Apache web server
  • MySQL database management system
  • Ruby on Rails
  • Mod Passenger Apache module

The How-To provides detailed instructions on the installation and explains what each step does, so that it can be easily follows by people experienced and new to the Ruby on Rails environment.


  • CentOS is installed and works
  • Apache is installed and works
  • MySQL is installed and works
  • Your are logged as root
  • The next steps are done successively without errors

yum install mod_passenger


rpm --import
yum install
yum install mod_passenger

Install Bundler

gem install bundler

Add the Bundler Boot and preinitializer code

For more info go to the Bundler site.

Create the Gemfile and register these gems in it

vi /var/www/redmine/Gemfile
# file: /var/www/redmine/Gemfile
source "" 
gem "rake", "0.8.3" 
gem "rack", "1.1.0" 
gem "i18n", "0.4.2" 
gem "rubytree", "0.5.2", :require => "tree" 
gem "RedCloth", "~>4.2.3", :require => "redcloth" # for CodeRay
gem "mysql" 
gem "coderay", "~>0.9.7" 
bundle install

Create the Redmine MySQL database

yum install mysql-server
chkconfig mysqld on
service mysqld start

For MySQL:
start the mysql client (mysql -u root -p) and enter the following commands

create database redmine character set utf8;
create user 'redmine'@'localhost' identified by 'my_password';
grant all privileges on redmine.* to 'redmine'@'localhost'; 

For versions of MySQL prior to 5.0.2 - skip the 'create user' step and instead:

 grant all privileges on redmine.* to 'redmine'@'localhost' identified by 'my_password';

Configure /var/www/redmine/config/database.yml (rename database.yml.example)

Set the production environment (optional)

Uncomment the following line in file redmine/config/environment.rb:

ENV['RAILS_ENV'] ||= 'production'

Generate the session store

RAILS_ENV=production bundle exec rake generate_session_store

Migrate the database models

RAILS_ENV=production bundle exec rake db:migrate

RAILS_ENV=production bundle exec rake redmine:load_default_data

Follow instructions.

Rename dispatch CGI files in /var/www/redmine/public/

mv dispatch.cgi.example dispatch.cgi
mv dispatch.fcgi.example dispatch.fcgi
mv dispatch.rb.example dispatch.rb

Edit .htaccess file for CGI dispatch configuration

mv htaccess.fcgi.example .htaccess

Chown and Chmod files for read/write access for the Apache user

cd ..
chown -R apache:apache redmine-1.x
chmod -R 755 redmine-1.x

Redmine should be fully installed now and fully usable
